BACKGROUND: To compare the clinical outcomes and visual quality following bilateral implantation of Vivity IOLs with mini-monovision.
METHODS: Patients who underwent sequential bilateral cataract surgery with implantation of Vivity EDOF IOLs at our institution were divided into two groups: Group A was designed with a myopic refraction of ≥ 0.5 D and < 1.0 D in the non-dominant eye, while the refractive target for the dominant eye was emmetropia. Group B exhibited emmetropic refractive targets bilaterally. Outcome measures evaluated at 1 month postoperatively included: monocular uncorrected distance visual acuity (UDVA), uncorrected intermediate visual acuity (UIVA), uncorrected near visual acuity (UNVA), monocular objective visual quality, monocular and binocular uncorrected defocus curves, VF-14 score, Quality of Vision (QoV) score and patient satisfaction.
RESULTS: The study comprised a total of 61 patients (122 eyes). Statistically significant differences were not observed between the groups in terms of UDVA, UIVA, mean modulation transfer function (MTF), Strehl ratio (SR), aberrations, VF-14 scores, QoV scores and satisfaction. In Group A, the UNVA of the non-dominant eye was superior to that of Group B (0.36 ± 0.05 vs. 0.54 ± 0.06 LogMAR, P=0.024). The defocus curve of the non-dominant eye revealed that Group A attained superior visual performance at defocus levels ranging from - 2.0D to -3.5D (0.50 m to 0.29 m). However, these differences did not achieve statistical significance.
CONCLUSION: The findings of this study indicate that bilateral implantation of EDOF IOLs with a mini-monovision design improves near visual acuity without significantly compromising distance visual acuity, visual quality or increasing aberrations.
